**r8col_test**,
a FORTRAN90 code which
calls r8col(), which
contains utility routines for R8COL's, that is,
double precision real MxN arrays, considered as N column vectors,
each of length M. The data may be thought of as a matrix of
multiple columns, and many operations will be carried out columnwise.

- r8col_test.f90, a sample calling program.
- r8col_test.sh, runs all the tests.
